A museum groundskeeper is creating a semicircular statuary garden with a diameter of 29 feet. There will be a fence around the garden. The fencing costs $7.25 per linear foot. About how much will the fencing cost altogether? Round to the nearest hundredth. Use 3.14 for π.

The fence will cost $330.09

Step-by-step explanation:

First we have to calculate the perimeter of the semicircle for that we use the following formula:

d = diameter = 29ft

s = perimeter of semicircle

π = 3.14

s = d * 1/2 * π

we replace the values that we know

s = 29ft * 1/2 * 3.14

s = 45.53ft

Now we multiply the number of feet by the price of 1 foot of fence

45.53 * $7.25 = 330.0925

Rounding to the nearest hundredth

$330.0925 = $330.09

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
